MH60T Trivia #551-575
This trivia series distills over 20 years of flight manual study into 500+ focused questions and answers, posted in 25 question sets. It’s not a substitute for the manual, but rather an aid to facilitate study and strengthen airmanship. During your review, ask yourself: How is this operationally relevant? Do I need to memorize it, or just be familiar with it? Should I review more on this topic?
- Q: Anti-ice reduces power available?
A: Up to 18%.
- Q: ECS on HOT reduces power available?
A: Up to 5%.
- Q: ECS on COLD LOW flow reduces power available?
A: Up to 4%.
- Q: ECS on COLD HIGH flow reduces power available?
A: Up to 7%.
- Q: APU fuel burn?
A: 170 lbs./hr.
- Q: With anti-ice on, what is the increase in fuel burn?
A: Approximately 84 lbs./hr. (not calculated in charts).
- Q: With ECS on, what is the increase in fuel burn?
A: Approximately 20 lbs./hr. (included in calculated charts).
- Q: When must de-ice, anti-ice systems be turned on?
A: 5°C in visible moisture.
- Q: With “normal” ice build-up, possible torque increase?
A: Up to 14%.
- Q: An increase of how much torque should mean urgent consideration to leave icing?
A: 10%. (Note torque in level flight at a consistent altitude and airspeed to establish a torque baseline).
- Q: A increase of how much torque means exit icing conditions immediately or land ASAP?
A: 20%. (Note torque in level flight at a consistent altitude and airspeed to establish a torque baseline).
- Q: With all de-ice and anti-ice systems working, flight in what type of icing is allowed?
A: Light, moderate if mission urgency dictates.
- Q: Icing descriptions?
A: Light – easily handled by ac de-ice/anti-ice systems. Moderate – ac de-ice/anti-ice systems are at capacity. Severe – ac de-ice/anti-ice cannot keep up.
- Q: When will the ECS always shutdown?
A: Starting engines, contingency power on.
- Q: When will ECS shutdown?
A: When air source is in engine, TGT above 851, anti-ice is turned on, de-ice is in auto and ice is detected-anti ice on, an underpressure exists.
- Q: Main Rotor de-ice is powered by what bus?
A: Monitor bus.
- Q: Tail Rotor de-ice is powered by what bus?
A: Secondary bus.
- Q: Main rotor de-ice needs what generators working?
A: Any two generators.
- Q: Flight is allowed in what turbulence?
A: Should avoid moderate or greater.
- Q: Turbulence airspeeds?
A: Light: blade stall – 10 knots. Moderate – 15 knots.
- Q: ITO procedure?
A: Climb power, wings level, three positive rates of climb (radalt, baralt, VSI) through 50′, nose 5°down.
- Q: Any two generators power which AC buses?
A: All five (#1 and #2 primary, AC ess, sec, monitor).
- Q: Which buses are powered with only one main generator and back up pump off?
A: All except the monitor.
- Q: Which buses are powered with only one main generator and back up pump on?
A: All except the monitor and secondary buses.
- Q: The monitor bus powers what items?
A: The main rotor de-ice.
